MEANS FOR STENCIL-PRINTING.

SPECIFICATION forming part of Letters Patent N 0. 443,801, datedDecember 30, 1890.

Application filed March 2, 1889. Serial No. 301,781, (No model.)

To all whom it may concern:

Be it known that we, JOHN W. SMITH, of Boston, Massachusetts, and HENRYL. HEISKELL, of Oxen Hill, Prince Georges County, Mary- 5 land, citizensof the United States, have invented certain new and useful Improvementsin Means forStencil-Printing; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying draw- 1ngs, and to theletters of reference marked thereon,which formapart of thisspecification.

:5 This invention has relation to that class of devices for reproducingor making manifold copies of letters, music, &c.; and it has for itsobjects the production of a convenientlyshaped, simple, and economicaldevice of that character that will obviate many disadvantages heretoforeexperienced with such devices.

To these ends our invention, which we denominate the milliograph,consists in certain novel features in the construction, arrangement, andcombination of parts, substantially as hereinafter described, andspecifically pointed out in the subjoined claims.

In the accompanying drawings, Figure 1 is 0 a perspective view of theherein-described milliograph as arranged, for transportation and when itis not in use, the corners of the several parts thereof being brokenaway to d sclose the relative position of said parts.

3 5 Fig. 2 is a similar view of our device, showing the same as arrangedfor use. Fig. 3 is a detail perspective view of a plate, which serveswhen the device is not in use as a lid or cover therefor, protect-in gthe interior parts thereof, and when in use as a surface upon which tocut the stencil. Fig. 4 is a transverse section taken on the line 00 wof Fig. 1. Fig. 5 is a transverse section through 3/ y of Fig. 2.

Like letters of reference mark the same parts in the several views.

The box or receptacle of our milliograph is composed of the leaves orparts A A, which are hinged together on one side, as shown at a a, andprovided with pivoted hooks b, and

pins Z) on their opposite sides, as shown in Figs. 1 and 2. The upperportion or leaf A of said receptacle is constructed of longitudinal andtransverse strips a a, thus forming a frame simply, while the lowerportion thereof is made preferably of a block of wood having its edgerecessed or cut away (see Figs. 4 and 5) to form upwardly and outwardlyextending projections, designated, respectively, by the letters 0 and0'. Upon the proj ection c the ink pad or supply D rests. Thisink-supply may be a plate formed of metal, glass, or other suitablematerial having the ink spread upon it in suitable quantity, or, ifpreferred, it may consist of cloth,felt,rub-

ber, rubber cloth, or other suitable pervious I or absorbent materialsaturated with ink and 7 adapted when pressure is applied to give off 4the ink.

B designates a plate, (shown in detail in Fig. 3,) preferablyconstructed of zinc or some similar metal, and formed with dependingprojections B and lips or flanges B, extending horizontally from theextremity of said projection B. An inverted flanged pan is thus formed,which is designed to form a lid or cover for the inilliograph when thelatter is not being used, protecting the interior parts of the same fromexterior influences, such as air and dust, the former of which wouldcause evaporation and consequent loss or deterioration of the ink, andthe latter gumming thereof, besides necessitating constant cleaning ofsaid interior parts by settling thereon, as will be readily understood.The platelS also forms a surface upon which to cut the stencil.

When it is desired to use our improved milliograph, it is necessary toremove said pan, and such removal is eifected by unlocking thereceptacle or box and raising the upper leaf thereof, when, as isobvious, access is had to the interior of said receptacle and the paneasily lifted therefrom.

The method of taking copies of circulars, letters, &c., by means of thehereinbefore-described device is as follows: A stencil C is made in anyusual manner by perforating the outline of the letters, figures, &c.,and for this purpose any of the ordinary and wcll-knowu perforating-pensmay be employed. The lid or pan upon which the stencil has been madehaving been removed and the stencil placed face downward in contact withthe ink pads 5 or supply, the device is ready for operation. now placethe sheet of paper upon which the copy is to be taken face downward onsaid reversed stencil and apply pressure to its upper surface, whichpressure forces the ink up xo through the punctures of said stencil ontosaid copy-sheet. Should the supply of ink become exhausted before thedesired number of copies have been made, the pad or plate upon which itwas spread can be readily rer moved, respread with ink, and replaced.One means referred to for applying the required pressure is shown inFig. 2, in which is delineated a roller E, the shaft F of which isjournaled in the respective extremities of a 2o 1' ra me G, which isprovided with a rearwardlyextending projection G, having a handle llthereon for convenience in using. \Ve do not i wish to be understood aslimiting ourselves to this form of means for applying pressure,

as any suitable means maybe employed without departing from the spiritof our invention.

Although we have described a particularlyconstructed frame upon which tomount our ink-pad and stencil, we do not desire to be 0 understood aslimiting ourselves to such construction. When desirable to makeimpressions by other means than the roller described,

we will build up our printing-surface differently. For instance, we maytake a sheet of metal as the ink-pad, ink it, place the reversed stencilupon it and the paper upon the stencil when we desire to make theimpression by passing it through a pair of suitable rolls, the object insuch case being to make the structure as thin as possible. \Ve may alsouse a plain wooden block for the ink-pad of such thickness that when thestencil is added the thickness will about equal the length of type. Thisstructure could then be used in 5 a printing or lithographic press. Bythis means of printing through a reversed stencil many objections whichexist when an inked roller is passed over a stencil are removed. 15 veryrolling by the inked roller tends to gum up, clog, and till thestencils, and specially prepared very expensive paper must be used.llhereisagreat ten dency, also, to soil the hands and the paper.

In operating this invention nothing but clean paper and clean rolls areused while taking impressions, and every impression tends rather toclean than clog upthc stencil. The stencil, always lying upon the inkedsurface, may be made of the fiimsiest oiled or waxed paper, splendidpractical results havingbeen obtained with the paper used to wrapcandies or caramels in.

By spreading different colors of ink upon the plate or pad-as, forinstance, in the spaces marked 3 and f in Fig. 5the copy maybe made ofdifferent colors; or, such dilterentcolored inks maybe dilferentlyarranged-as, for instance, in sueha manner asto print a seal,trade-mark, or autograph in a color different from the body of the copy.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent in the linited States, is-

The combination, with a base A, having an upwardly-exten(lingproject-ion c in its central portion and ontwardly-extending projections0 upon its sides, of an ink-pad supported by the said upward projection,a frame hinged to the said base surrounding the upward projection andresting upon the outward projections thereon, and a metallic cover having dependent flanged sides contained between the said base and frame,the top of the said cover being above the said pad, as described.

In testimony whereof we alti x our signatures in presence of twowitnesses.
